Threatened Species Recovery Hub researchers presented at the recent Species on the Move International Conference in Hobart, including Hub Director Hugh Possingham.
Professor Possingham presented on the role of decision science in moving species outside their normal range in response to climate, and other, change.
“There are a whole lot of reasons why we might want to relocate an animal to somewhere it's never been, and it presents a lot of challenges.”
“Decisions about moving species are hard, but if we avoid that decision, and do nothing, extinctions will occur. Even if we lack full information we can make good decisions about moving species outside their original range in the name of conservation.”
“The species on the move conference brought together managers, researchers and policy makers from across Australasia to tackle contentious issues in conservation science and management in a rapidly changing world. There is nothing like face-to-face talks, panels and discussions to hammer out solutions to difficult problems,” said Professor Possingham.
Other TSR Hub presenters included:
The world is changing. Some of this change is planned and desirable. But much else is an unwanted consequence of the expansion of the human species. Those unwanted impacts will affect our lives and those of our descendants.
After undergraduate majors in Geography, Environmental Science and Botany, I did my PhD on native grasslands. I was struck by how these Critically Endangered ecosystems existing right on the edge of my city were being lost without most people even knowing about them – or understanding what amazing, super diverse ecosystems they are.
What influences where birds choose to nest? About 15% of Australian birds, or 114 species, need tree hollows for breeding or shelter. The number of hollow-bearing trees is declining due to timber harvesting and development.
Fish need to move to find food, escape predators and reach suitable habitat for reproduction. Dams, weirs and culverts can create barriers that fragment habitats, isolating fish populations. An Australian innovation, however, promises to help dwindling fish populations in Australia and worldwide.
Endangered forty-spotted pardalote nestlings are falling prey to the larvae of a blood-feeding fly parasite. Researcher Fernanda Alves, reports on experiments that encourage forty-spotted pardalotes to ‘self-fumigate’ their nests by incorporating chicken feathers treated with a bird-safe insecticide.
